There's a brief thought - "What...?" - before Walter manages to ground himself in the fact that this is a restaurant, no one other than Ben is looking at him right now (or even, given a nervous glance-about, seems to be listening in their direction), and there's food he hasn't even really smelled yet in front of him.

"Right." He takes in a few small bites, blowing once at the rising steam.

"Hnnn. No." There was the chance that even just thinking about it could allow him to see what happened next, but so much of his mind goes afire with "NO!" at the idea of another Echo that he really doesn't want to.
